You can do this problem algebraically by assigning variables. If Sara has 3 times Sam we can say Sam is x and Sara is 3x and together they have 28.

Which looks like
3x + x = 28
4x = 28 ( divide both side by 4)
x= 7

So Sara have 3x which after substitution or replacement looks like this
3 x 7 = 21.
So Sara have 21 pencil eraser.

4/3x + 1/6x = 36 (solve for x please help I have no idea what it is!!!!!!!
ElenaW [278]

Answer:

x = 24

Step-by-step explanation:

\frac{4}{3}x + \frac{1}{6}x = 36

Make the denominator the same by multiplying the first fraction by 2 to make both denominators 6.

\frac{8}{6}x + \frac{1}{6}x = 36

Now we can calculate the numerators and keep the denominators the same.

\frac{9}{6}x = 36

Find x.

\frac{6}{6}x = \frac{6}{9} × 36

x = 24

A=42°, b=10, c=12. What is the length of a to the nearest tentH
Digiron [165]

The length of a in the triangle to the nearest tenth is 8.1 units.

<h3>How to find side of a triangle?</h3>

The side a of the triangle can be found using cosine formula.

Therefore,

a²= b² + c² - 2bc cos A

a² = 10² + 12² - 2 × 10 × 12 cos 42°

a² = 100 + 144 - 240cos 42

a² = 244 - 178.354758115

a = √65.6453

a = 8.10217871933

a = 8.1
